Core supplies VDD_CORE, VDDA_CORE_CSI_DSI, VDDA_CORE_DSI_CLK, VDDA_CORE_USB, and VDDA_DDR_PLL0 are recommended to be powered by the same power source and can be operated at 0.75 V or 0.85 V. (valid operating ranges defined in the ROC table). When these supplies are operating at 0.75 V, it is recommended to ramp 0.75 V prior to all 0.85 V supplies. Setting the core supply to 0.8 V is not an allowed option and there is no range defined for a nominal operating voltage of 0.8 V.
Core supplies VDD_MMC0 and VDDA_0P85_DLL_MMC0 are specified to operate at 0.85 V when MMC0 is used. It is recommended to connect VDD_MMC0 and VDD_0P85_DLL_MMC0 to the same power source as VDD_CORE when MMC0 is not used.
VDDR_CORE is specified to operate only at 0.85 V. When VDD_CORE is operating at 0.85 V, VDD_CORE and VDDR_CORE are recommended to be powered by the same source (ramp together).
VDDS_OSC0 and VDDA_MCU supplies are recommended to be connected always.
The processor includes multiple analog supply pins that provide power to sensitive analog circuitry like VDDA_MCU, VDDA_PLLx [x=0..4], VDDA_1P8_CSI_DSI and VDDA_1P8_OLDI0. Filtered (ferrite) power supplies are recommended.
